Calimocho originated in the Basque region of Spain but has spread throughout the entire country and to many other parts of the world.
I gave this just 3 stars because I don't really care for sweet drinks like this one. But it's worth trying at least once none the less. About this recipe...Any cola will not work for this drink. You must use Coca Cola or you’re not making Kalimotxo properly. Coca Cola is very important because the other brands of colas are too sweet and that destroys the mix. The other thing this recipe and its direction leave out is that it has to be bad wine, this is fundamental, because kalimotxo with good wine tastes worse and you are just wasting a good wine. The wine should be bitter, because Coca Cola is sweet enough and the mix has to be compensated for. The other thing is the mixing of this drink, you want to maintain as much of the gases from the coke as possible, so be careful with doing the mixing. I recommend you us an empty 2 liter bottle, carefully fill about half the bottle with the coke, then add the bad red wine, then carefully fill with the rest of the coke. Close the bottle and gently rock it about 4 or 5 times to mix, remember, your attempting to maintain as much of the gasses of the coke as possible. Oh yes, the other thing about Kalimotxo is try not to drink too much of it, it will leave you with one nasty hangover the next day after drinking all that sugar. - 09 Sep 2007 (Review from Allrecipes USA and Canada)
I've been mixing red wine and cola for a while now and am glad that I'm not the only one. I like it on days the red wine is tasting too heavy. - 19 Dec 2010 (Review from Allrecipes USA and Canada)
I spent two weeks in Basque country this summer and drank these frequently. They use common table wine with ONLY COCA COLA. - 23 Oct 2009 (Review from Allrecipes USA and Canada)
